Documentation

Hydrogen safety documentation should be made available to all personnel and should cover topics specific to your facility and any hydrogen equipment and processes there:

• Roles and responsibilities
• Availability of hydrogen safety training courses
• Safety planning process
• Current hydrogen safety plans
• Results of the most recent hydrogen safety inspections in your facility
• Operating and maintenance procedures for hydrogen systems
• Reports on any hydrogen incidents or near-misses in your facility
• Information pertaining to the technology of any hydrogen processes, including:
  • A block flow diagram or simplified process flow diagram;
  • Process chemistry;
  • Maximum intended inventory;
  • Safe upper and lower limits for such items as temperatures, pressures, flows, or compositions; and,
  • An evaluation of the consequences of deviations, including those affecting the safety and health of employees.
• Information pertaining to the equipment in the process including:
  • Dimensions and layout;
  • Piping and instrument diagrams (P&IDs);
  • Materials of construction
  • Electrical classification;
  • Relief system design and design basis;
  • Ventilation system design;
  • Design codes and standards employed;
  • Material and energy balances; and
  • Safety systems (e.g., interlocks, detection, and suppression systems).
• General hydrogen safety information (a library of applicable codes and standards, regulations, industry brochures, etc.)

Work documentation (e.g., work orders, baseline drawings) should always reflect the current hydrogen system configuration.
